(Spock leaves the bridge - upon leaving the turbolift, he encounters a crewman with a red stained paintbrush laughing hysterically who really doesn't seem to notice Spock's approach)

Spock: Crewman, report to the lab!

(The crewman begins to walk away, Spock continues on his way until he happens on another scene in an adjacent corridor, Yeoman Rand is attempting to get to the turbolift but another crewman is standing in her way)
